Best USB flash drives 2017

Modern USB memory sticks (or flash drives as they're often known) can hold incredible amounts of storage these days - we're talking gigabytes of the stuff, which means buying the best USB memory stick money can buy can be incredibly important.

That's because the larger capacity of USB memory stick, the more data we store on them, and we need to know that our data will be safe and secure - especially if you are storing files for work, or adding irreplaceable files (such as family photos) to the flash drives.

To help you choose what kind of USB storage is right for you, we've put together this list of the best USB flash drives you can buy today.

USB memory sticks are small, spacious and incredibly versatile. We use them in the office all the time, for moving everything from screenshots to benchmark suites.

Because we rely on these small USB sticks to hold on to our important information, it's essential to find a USB stick that meets our demands - including portability, capacity and security.

To that end, we've listed the best USB sticks that match all of those requirements below, so you can buy with confidence.

• If USB memory sticks are either too expensive (for the amount of storage you're planning to use) or their capacities are simply not high enough (or you tend to lose them too often), then why not check our best external hard disk drive deals in the UK.

If you want one of the fastest possible USB memory sticks, then the Patriot Supersonic Rage 2 is definitely the one for you. Sure, the price is high, but we were blown away with how fast the device is. If you need to move around large files quickly, then this is definitely worth the price.

It also comes with 128GB of storage space, which is a phenomenal amount of storage to carry around in your pocket. Just make sure you don't lose it!

Over the past two years or so, the rise in wholesale transportation costs has made it uneconomical for retailers to sell USB flash drives that were too small, with the cost of postage and packaging actually constituting the biggest portion of the selling price.

The DT100 G3 is the most affordable 64GB USB 3.0 drive on the market with read/write speeds of 150Mbps and 70Mbps respectively. Also consider the Kingston Technology DataTraveler G4 (available for £10.89 at Amazon) and the Sandisk Ultra Dual at £11.99 from Base which allows you to transfer your files between OTG-enabled Android smartphones and tablets.

The SanDisk Extreme CZ80 is a brilliantly priced USB drive that offers plenty of storage space and file transfer speeds. Although it's priced more towards the budget end of USB sticks, the performance is anything but budget - this is a very speedy little performer.

The slide-out design of this stick means you can tuck the USB interface into the body when not in use, minimising the risk of it getting damaged while you're carrying it around.

This is the cheapest USB 3.0 drive on the market on a per-GB basis at 13p and the sweet spot in the market. It comes with a two-year warranty and a capless/retractable cap design. 

Worth nothing that Verbatim - a very well known Japanese storage and memory manufacturer - sells it for £69 on its website and while there's no advertised read write speeds, it is likely to be fast.

Another memory vendor that turned into a player in the USB market as well. which features a capped design as well as read/write speeds of 80Mbps and 20Mbps respectively. 

These are not super fast speeds and if you want something with more oomph then check out some of the other USB drives in this roundup.

A USB 3.1 drive (compatible with USB 3.0 and 2.0) from one of the most established memory players on the market but a relative newcomer to this segment.

It has a zinc alloy body with aluminium accent and reaches read/write speeds of 380Mbps and 70Mbps respectively. No slouch and one that comes with a five-year warranty.

We're solidly in premium territory with this model; not only does it offer absurdly high read speeds of up to 450Mbps thanks to Samsung's own 3D V-NAND technology, it also comes with a three-year warranty and has a USB Type C connector. Note that it is much bigger than a traditional flash drive and costs about five times a spinning hard drive of a similar capacity.

In comparison, a 1TB SSD like the Samsung EVO 850 costs just £240. It comes with V-NAND based like the Samsung Portable T1 and it does boast speeds of 530Mbps and 520Mbps in read/write mode respectively. Note that you will need to get a separate enclosure to get it to work with a standard USB port.

If you don't want a USB stick jutting out of your laptop or tablet while you use it, then a low profile USB stick is a good choice, and the SanDisk Ultra Fit CZ43 is an excellent choice. It's small and light enough to easy carry around, and when it's plugged into your laptop it doesn't stick out much from the body.

It's also very cheap, at around £10 for the 32GB version, with 64GB and 128GB versions also available. It's not quite as fast as many of the other USB memory sticks we mention here, but if you want a small form factor USB stick, it's worth the trade-off.

How to choose your USB memory sticks?

• It's not worth looking for memory sticks with capacities smaller than 64GB simply because the price premium you pay for twice or four times the storage is tiny.
• Make sure you include delivery price when doing the numbers as quite often you end up paying more for the postage than the drive itself, particularly for low cost models.
• USB 2.0 is sufficient for smaller capacities but not for bigger ones where write speeds can be sluggish. Larger flash drives (128GB or more) often come only with a USB 3.0 connector.
• If you plan to move files to and from portable devices (tablets or smartphones), consider a memory stick with a microUSB connector and a full size USB one.
• Avoid buying your memory sticks from vendors with few feedbacks on auction websites as these drives might turn out to be fake. All the vendors listed below are tried and trusted ones.
• Above 128GB, you might want to consider a SSD if you want ruggedness, portability, versatility and better performance without the cost.
• Note that all the capacities are likely to be much less than stated when they are formatted and when mounted on an operating system.
